The owners of a 3-story, 60-foot houseboat docked in Hudson, Wisconsin won't be doing any cruising any time soon after the large vessel sunk in the St. Croix River sometime late Thursday or early Friday.

KARE 11 photojournalist Bob Crippa says the first two levels of the boat are completely under water.

The owner of Hudson-Afton Cruise Lines, where the boat is docked, discovered the situation Friday morning around 4 a.m. and immediately called the owners and an environmental company. Ex-Environmental put pads and booms in the river to surround the boat and contain any oil or diesel that might leak out.

At this point it is unclear what caused the houseboat to sink, but one person on scene estimated it could take up to $30,000 or so for salvage crews to remove the 60-footer from the river.
